Source of validity: Traditional
Rating (out of 5): 3

The kola nut, derived from trees of the genus Cola, has a long history of traditional use in West African cultures, primarily as a stimulant and ceremonial item. Its traditional application for stimulating the sympathetic nervous system arises from its naturally high caffeine content, which is known to increase alertness, reduce fatigue, and enhance physical energy. Caffeine is a well-known central nervous system stimulant that acts by antagonizing adenosine receptors, subsequently increasing the release of neurotransmitters such as norepinephrine and dopamine—both of which are closely involved in sympathetic nervous system activation.

While modern science acknowledges the effects of caffeine on the sympathetic nervous system—including increased heart rate, elevated blood pressure, and enhanced metabolic rate—direct scientific research specifically on kola nut (as opposed to isolated caffeine or other sources) remains limited. Most scientific validation for its sympathetic nervous system effects is extrapolated from its caffeine content rather than from studies on the kola nut itself. Thus, the justification for its use to support the sympathetic nervous system is grounded primarily in traditional knowledge and supported by established pharmacology of caffeine, rather than robust clinical trials on kola nut as an herb.

In summary, the use of kola nut to support the sympathetic nervous system is mostly traditional, with moderate evidence based on the known effects of its constituent caffeine, but lacking in specific, high-quality studies focused solely on the nut itself.
